what should i do ?

i got off nexplanon in august , me and my fiancé have been trying for a baby with no luck , my last period was 5 days late and ended up coming , i felt like i had all the symptoms under the moon before my period started . this time around we weren’t planning and i’ve tested before and they were negative , at this point i’m pushing nearly 7 days late my nipples are sensitive and i had slight nausea today , so far absolutely no sign of my period . i’ve also been feeling very bloated for the past week or two . what should i do ?
